Default Slight lurch upon startup...

Ok so lately I have noticed that when I start my truck, it will slightly jump forward. It's barely noticeable, but I notice even the smallest of things that are out of the ordinary... What could be the problem?

Is it fate that I just saw a very nice looking, higher mileage, 2001 Blazer Trailblazer for dirt cheap at a local used car lot?... Only thing I could see wrong with it was a bit of rust on the doors down on the lower front corner. Nothing that I couldn't get fixed for dirt cheap.

Yup, it's on initial startup. It doesn't do it all the time. Seems really erratic. No codes either, just scanned it before I posted.

Transmission was serviced around 4000 miles ago. I need to drop the pan again anyway to install a drain plug.

Strange. Is this on the Bravada? or did you buy a trail Blazer?

It's on the Bravada.

I just stopped in and looked at an '01 Blazer Trailblazer on a used car lot at lunch today. But, its a lot more miles than my Bravada has (125k miles vs 82k miles on the Bravada) and it needs ball joints, brakes, shocks, full tune up, and it may have a rear main seal leak. All for $4900... Oh yeah, needs tires too! LOL. And I already mentioned the rust...

My 2000 blazer does the exact same thing. It just rocks forward a bit on startup. It never worries me though, I've come to accept it as a characteristic of the vehicle.
